g To all whom it may concern:

Be it known that I, HENRY Fon'r FLOW- nns, acitizen of the United States, and a resident of the city of New York, borough of Manhattamin the county and State of New York, have invented certain new and useful Improvements in Dumping-Cars, of. which the following is a specification.

to a dumping car The invention relates havlng a bodywhich 1s movable horizontally across the underframe' and which can be tilted so as to'discharge the load.

One object of the present invention is to construct a car so that it will have a tilting which, at the same'time, will be able to dea body that will he maintained at a minimum heightabove the underfram'e and track and posit its lading when dumped at a point a sufiicient distance from a railway track upon which the car is located to enable other cars without obstruction.

The invention also involves an operating 1 mechanism for moving the tiltingbody or 1 cars of this type are subjecte dumping body as it may is herein shown no part thereof projects or extends above or overlies the body. This operating mechanism or ,body dumping I mechanism as it may be called is constructed so that it does not obstruct or deter in any manner the loading ofthe material on the b0 y and it is also constructed so that there isdittle likelihood of its becoming damaged use to which or injured during the ordina As showing a specific embodiment ofthe invention reference'ismade to the accom panying drawings forming a part of this speclfication, and in which drawings,

Figure 1 is a plan view of the underframe including the end platforms. In this View there is also shown on one of the end platforms the casing of' the dumping mecha- .nism, the casing of the motor which operates the dumpingmechanism, the casing of the "the dumping mechanism and the casing of Worm gear reducer between the motor and tially broken away. In this figure the the line 55 of Fig.

. ried on the body and a ing block that is carried be called to either side of the unde'rfram'e. According to the specific form of operating mechanism which body is shown in position on the underframe and a center compartment of the body is the one which has been broken away.

i Fig. 8 is an .end sectional elevation taken between the diaphragms or sides of the casing of the dumping mechanism, for instance as on the line 3-3 of Fig. 2. In this figure 3 there is indicated the manner in which the dumping mechanism can operate to cause the moving and tilting of the body. There is alsoindicated inthis figure automatic door operating mechanism which causes the side doors to be released as the body is tilted.-

, Fig. 5 is a sectional elevation taken as on Fig. 5is a vertical view, tion, showing the hitch casting that is carportion of a resistby the casing of the dumping mechanism. The function of the resisting member is to cooperate with the hitch casting in a manner to insure the body being retained in horizontal position on the underframe until the body has been moved from its central or normal position on the unclerframe.

Fig. 6 is a sectional plan View of Fig. 7 taken as on the line .6--6 of said Fig. 7. In Fig. 6 the controller casing is indicated only by broken lines; this figure in conjunction with Fig. '7 shows the connecting linksof the automatic reversing mechanism whereby the controller is actuated when the body approaches its extreme travel. to the side of the car. This actuation is accomplished by a hitch casting or a member on the body of the car engaging a link of the automatic reversi-ng mechanism.

Fig. 7 is a partial end elevation of the operating end of the car. This View shows the controller and Wormgear reducer where by the dumping mechanism can be actuated by means of the motor.

Fig. 8 is an end elevation; Fig. .9 is a side elevation and Fig. 10 is a plan of a portion of the hitch casting together with What are known as thimble castings that are located on'the hitch casting and portions of the ropes which extend over the thimble castings. There is a hitch casting together with thimble castings and ropes OJj-sbhhfil flexible connectors at each end offlghe car.

Figs. 9 and 10 have been provided so as to clearly show the construction which allows the hitch casting to turn during the tilting operation in the thimble castings over which the ropes pass. The thimblo castings on each trunnion are separated or parted to allow the tension in the ropes to be equalized without the ropes having to slip in the respective grooves. in the thiinblo castings, within which the ropes are posilioned.

a chain F of reducing gears. This chain mm'ay be referred to as a worm gear reducer because 11; comprlsesvvorms or screws WOl'king in worm gear wheels. The motor is con trolled by a controller G which in turn can be automatically moved or actuated by what is known as a hitch casting ll. This casting is on the car body and it effects the movement of the controller G through the me;

dium of a reversing" or stopping nieehanisn'i =K when the body has approached its extreme travel to the side of the car. Over this casting or'over members located uponit. there passes in a manner which will be herein,- afterdescrtbed flexible connectors-to wit, ropes wh ch are actrnitedfrom a sha'l tdriven by the motor throngh the. chain of reducing gearing. These ropes and shafts just referred to constitute a part: of the dumping mechanism and will be hereinafter described more in detail.

The auton'iatic stopping or reversing niccl'ranism ll: which actuates the controller comprises horizontally extending links L This last mentioned mechanism will.-

.lhis mecham'srn D is actuated. by the rnottor E through I and vertically extending links Ill. The adjaeentv or inner ends of the hrniizont'ally extending" links ll arceoxmeeted to a crank 1 which is on the controller shaft (l. while. the. outer ends of the links L are carried by the vertically extending links M by being pivotally connected to the lower ends of said links M. The links L and M are arranged so that; they normally occupy the position indicated by the full lines in t ig. (3 and by the lines made with short dashes in Fig. 7, but; they canbe displaced by hand in the manner indicated by the lines made with long dashes and (lots in Figs. (3 and 7. These links will of courseoccnpy, their normal position until the force. is applied as by hand to move them to the position where an operating cir- .cuit. for the motor will be closed, and the links will occupy this last ll'iOlli-lOllBfl position until they are restored to their normal position---or even moved to a position Where a reverse. motor circuit will be elosedby the hitch e: 'ng ll when the car body has been moved sidewisex certain distance from its normal central po. ion.

In Figs. 6 and '7 the hitch casting is indicated by the lines made with dashes and dots and this is the position which the hitch casting occupies when it is about to restore the links L and M oi the automatic reversing mechanism K'l'o their normal-position or at; least; when it is about tdmove the links from the position in which they have been placed by'the hand Opelllt ltill of the controller.

The movement ot the links L and M is sutl'icient, asprevionsly.indicated, to turn the controller shaft O in the proper manner to either shutoil the motor 1' completely reverse the motor according, to the conditions desired. It will also be noted that the handle l can be utilized at. any time to shut oil the motor when desired and that. it can also be utilized to open either the forward circuit or the reverse circuit of the motor at; all times. except, when the car body is at the extreme travel to one side or the other of the. ear in which case the etml'rollor handle can be positioned only in the proper direction to open a reverse circuit so as to start; to more the body toward its normal central position. A

Theunder-frame cknnprises two center sills l and 2 and two longitudinally extending side sills 3 and l. the latter of which are positioned adjacent to or over side. bearings 5 and (l. rcspcctively. which are on the trucks. The ends of these several sills are a gears as they roll along and mesh Wit the' connected to what may be referred to as curved end sills 7, one at each end of the car.

to as the bolster constructionand this figure shows how the center and side 51115 are i built into the bolster. This bolster has side 15 shows how built in the transverse members. Upon each of these tracks rollers 10 and 11 rest} and theserollers are cut out or notched at, 10 and 11% so that they will in fact operate as projections 9 on the track. These rclllers are connected'by links 23 whereby they will operate in pairs and there extends from the center of each ofthese rollers what I considered as a projecting shaft. These projecting crence character 24 and they are constructed so that they can be engaged by roller stop body.,

castings 25'which 'are secured to the These stop castings engage the projecting shafts as the body approaches the end horizontal movement toward the side of the car. The parts 26 onthe stop roller castings are the parts-which engage the projecting shafts 24 on the rollers and these stop castings areprov'ided to limit the horizontal movement of the body toward the slde of the car and to hold the body in a definite posiijlOIld'GlfllllVG to the rollers whereby during the tilting movement of the body it and the roller will swing together upon tracks 8 with the rollers operating asrockers. The carlbody is shaped sofas to receive these rollers and in fac't'in the central portions of the car there-are provided transversely extending pockets, as at'27' (see Fig. 2). It will be noted that, in order that the car body 10 and 11 in the rollers.

shall have the movement above described, it is necessary the body be provided with track members 27 which rest upon the rollers. These track members each have a series of transversely extending depending rivet heads that provide teeth or projections 2.8 which mesh with or, fit into the notches manifest that with the toothed construction on both the body and the under-frame tracks the car will always be' maintained in a proper position relative to the underframe as the body moves on the rollers transversely of the underframe and as the rollers move transversely of and on the underframe. In other words, the body cannot become cramped or displaced due to a slipping of ,The. carshown in Fig. 16- illustrates what, may be referred transverse members or needle.

shafts are designated'by the 'nefand a Worm wheel of its Finally both of these It will thus be the body on the rollers, or due to a slipping of the rollers on the underfraine.

the drawings .in this application is an improvement upon the car. shown in the drawings of an application filed by me in the United States Patent Office on November 27th, 1914, to wit, Application Serial No. 874,165. In said application-an operating shaft of the dumping mechanism extends from one end of the car body to the other and-is located over the car body.

According to the form of car shown in the present application a construction has been provided wherein the operating shaft is located below the body instead of above it. The shaft just referred to is designated by the reference'character 12. This shaft is located in the space between the center sills 1 and 2 and it is operated as previously indicated by the motor E through the worm gear reducer F. This worm gear reducer comprises .a worm or screw 29 which is driven by the motor E, a worm wheel 30 driven by the worm 29, a worm 29 connected to and driven by worm wheel 30, 30' which is driven by the .worm 29'. The Worm wheel 30 .is the member that is connected to and that drives the/operating shaft 12. This shaft extends the full 'length of the body and a distance beyond it and there are provided at each end of the shaft winding drums 13 overwhich the ropes or flexible connectors 1.5 and 16 pass or about which they are wound. From an inspection of Fig. 3 it will be observed that the flexible connector 15, passes over and in engagement with the thimble castingl'? and is in to the hitch casting. From the thimble castings the two parts 15 and 15 of the rope pass over an idler wheel or sheaves 18, and finall both of these parts pass over and III engagement with the winding drum 13." Similarly the rope or flexible connector 16 passes over the thimble casting 19 and is thus in effect secured or hitched to the hitch casting upon which the thimble castings are located. Each and .16" passes over an idler wheel 20. parts pass over and in engagement with the winding drum 13. Whlle the ropes Y15 and 16 scribed as being two different members still t ey may, as a matter of fact, constitute two e same rope and which parts may be considered to be connected.

rom an inspection of this figure it will also be observed that the hitch casting is so arrangedthat when the stop roller castings 25 strike the projecting shafts on the rollers the center of the hitch casting will substantially coincide with the pitch line of the rollers. In order to take up any slack in the ropes or flexible connectors there is proeffect secured or hitched part of the rope, to wit, 16

have been de-.

vided a tightening, sheave 32 carried in a. yoke 33, the latter of which. is held inrotracted position by a compression spring 3 A nut 35 is on the thrtaidcd-steui end of the yoke and serves as a means for regulating the force which the spring! 34- exerts upon the yolv and eonstau ently the force which the tightening sheave exc', s upon the ropes. From an inspection of Fig. 3 it will he observed that this spring forces the sheave .32 downwardly against the two portions of the rope It? and thus maintains taut'the entire set of ilcXible conuectoi's which extends around the hitch castings over the idler sheaves or wheels 18 and 20 to the winding drum or drums 13. The center o'l'- gravity of the car body and the parts movable thcrewith is approximatel 1 at the point marked C. S. It has been previously pointed out that the body moves transversely of the. under-frame as the body moves on the rollers and as the rollers in turn travel along the tracks on the underframe. This movement continues until. the. stop members on the body engage the projecting; shafts it on the rollers. From then on the further movement oi" the body tends to take place.

with the rollers acting as rockers. As. however, the motor has been stopped betm'ethc body assumes its full tilted position the set of flexible connectm-s 16* and 16" which are their heldsupposing for example the war body to have been moved to the right of the underiirame restrain the further outward movemento'li the hitch casting; that. is secured to the car body. ity of the car body is now to the right of the vertical plane passing through the centers of the right hand rollers and. hence the body tends to continue to assume a. farther tilted position. As the body, however. is restrained from moving outwardly, due to this restrained efiect on the part of the tlexible connectors or ropes l6 and 16*, the body will not movefarther on the rollers as rockers, but it will tend to swing on the upper portion of the rollers. This swing inp; about the upper portion of the rockers causes the center oil irravity of the body to be lifted, so to speak. and causes the rollers to be forced to the left a shortdistaucc dependent upon the amount of further movement of the body tm ard t'ull tilted position. The raising of the center of gravity of the body during this continued movement has the effect of absorbing; the momentun'i or energy which the body and its contained load had acquired during the irst portion of the tilting operation and hence the body comes to the end of its "full tilted-position very graduallyand [it has at. the end oi this period only a small amount. it any. of accumulated energy, the greater part of the energy having been t'absorbetfl by the energy itself raising the center of {gravity of the The center of gran car body at each end of the latter. The

. hitch castings and the flexible connectors are positioned so that the line of forcewhich may be referred to as -a restraining forcerestrains the body from substantial outward Y the handle 40 and movement during the last portion of the tilting ()PC'titlLlOIl. Not only the body is restrained trom this further outward movement-but also the'rollers about which the body previously swung as rockers. This line of force is located above the center of the rollers, which acted as rockers, thusbeing located in an advantageous positionto accomplisl'z this restraining operation. The tracks at the car body are, of course, above the center o t. theyrollers and the continued angularmovement of the car body,-without a continued outward movement of the car body, willrcsult in the li'fting of the center of gravity, or will at least. prevent the lower ingot the center of gravity of the car body, or the center of gravity of the combined body and load, if a. load isin the body. i The door gear mechanism or the door latch gear mechanismas it may be called is substan tially the same as the corresponding mechanism which is cleariy and fully described in the application Serial No. 874,165 above. relirred to. In the pending; application just referred to ti'l'iere is found what is designatcd as a shaft operating handle 40, a stop or locking-bolt H which is located on the nndertrame, a slotted lever 38 and a bellcraul; lever 37. The corresponding parts in this application-are designated by the refer ence characters 40. it-1., 35: and 37. In other words. these four parts bear the same reference characters in both applications with the. exception of the stop or bolt which in the pendingapplication is designated by the reference character H and in the present application by ail.

An inspection of Figs. 11 12 and 13 will make it clear that the center" and side sills 2 and tare connected to the curved end sills 7 by means of the angle irons 50, 51 and 52. To the underside of the end sill 7 there is secured what may be referred to as the apron Thisapron is in fact a curved channel member which maybe considered as a de; pending portion of the end sill. To the underside of the ends of the center sills there is also secured channel members 54. A bar 55 is located at each end of the car and eX- tends the full width thereof. This bar is secured in any suitable manner, as at 56 and 57 respectively, to the ends of the depending curved member 53 and to the underside of the members 54. To this transversely extending bar 55 and the underside of the members 54 there is secured a curved memher or plate, so to speak, 58. The function of this curved plate 58 is to serve as a sup port for the free end of a swinging yoke or connecting link, the fixed end of which link is carried in the member 59.- Very frequently with cars ofthe class described it is found advisable to force the car along the track even while the body is in its tilted po sition. This of course brings more or less of a strain where the body is supported on the underframe, especially if the lower portions of the body or the swinging doors are in engagement withthe lading which has been dumped.

In order to take care of the thrust which is transmitted from the body to the underframe at this time there are provided gusset plates or brace members 60 at each end of the car. These gusset plates or members are located over the side sills and extend to the upper portion of the transverse diaphragms or casing members or the dumping or op-v erating mechanism D. The construction just referred to -is shown in Figs. 2, 4, 5 and 5 and from these figures it will be clear that any blow due to the longitudinal movement of the body relative to the underframe is transmitted first to the depending flange of the angle iron, 61 through the plate 62 of the dumping or operating mechanism D, the gusset plates or braces 60, the end or platform floor plates which are on the sills and finally to the side sills themselves,

In order that the body may be prevented from raising relative to the underfraine when the body is in thecentral position on the underframe there is provided a block or resisting member 63 which is secured near the central portion of the angle iron 61. This block or resisting member is clearly shown. in Figs. 3 and 5*.

In regard to the dumping features of this car, it will-be observed the car is constructed so that the kinetic energy acquired by 'the bedy---rmd also by such oi itsload as is retaincri -during the first portion of its tilting 1,eee,seo

operation is converted into potential energy as the kinetic energy is employed to effect a raising of the center of gravity of the car body and a corresponding raising of such of the load as is retained therein.

The improvements herein set forth are not limited to the precise construction and arrangement shown and described, for they may be embodied in various forms and modi fications without departing from the spirit and scope of the invention.

A car of the class described comprising in combination an under-frame, a body mounted upon the underframe so as to move transversely relative thereto, flexible connectors connected or hitched to the body, passing over idlers at the sides of the car and thence to winding drums on the under- 7 frame, and means on the underframe that engage said flexible connectors so as to maintain them taut.

18. A car of the class described having in combination an underframe, a car "body mounted on the underframe so as to move transversely relative thereto, flexible ropes connected or hitched to the body, passing over idler 0r sheave wheels at the ri'ghtand left hand of the car and thence over winding drums located at the central portion of the ear, and a, tensioning device having spring means for maintaining the flexible connectors taut. 1

19. A car of the class described comprising in combination an underframe having transversely extending tracks, pairs of rollers mounted upon said tracks,a car body 110 having transversely extending tracks which rest upon said rollers, stop memberscarried by said body and arranged to engage said rollers when the car body has been moved the desired distance relative to the undernectors which pass over wheels that are on the underframe 'and'are secured to the car body whereby after the car body is swung for a limited distance on a part ofthe rollers as rockers further movement of'the car body outwardly will be restrained by the flexible connectors, the arrangement of the parts and the construction being such that with a further tilting of the car body the center of gravity of the car body will be raised due to the car body swinging on and relative to rollers with which it has previously 5 rung as rockers.

mounted upon the under-frame so that it can be tilted relatively thereto, a casting on the li car-body. a transversely extending member carried on the undert'rame with which the sends of said casting will engage when the car body moves longitudinally relative to the undcrframe when the body isin its imrmal position relative to the nnderframe, and gus set plates or braces for bracing the trans- 10 verse member when thus engaged by said castin 21. A car of the class described. compris-' ing in combination an under-frame having side sills a tilting car body mounted upon the underfranie so that it-can move trans versely relative o the under-frame, a hitch casting at each end of the car body, transversely extending members carried by the underframc and arranged to be engaged by said hitch castings when the car body moves longitlulinally relative to the under-frame, and gusset plates or braces extending from the side sills of the nndert'rzime to said transversely extending members.

-r A car of the class described having in combination an imderframe, a car body mounted on the um lerframe so as to move transversely relative thereto a hitch casting; carried by the car 0 and a transversely extending member 'located at each end of the car'body and carried by the undcrlramc, which transversely extendingincn'ibers are provided with resistance blocks located above and adjacent to the hitch castings when the car body is in its central position.

A dumping car of the class described comprising in combination an underframe having horizontally and 0 tending tracks, a pair of rollers mounted upon and movable along each of tracks, a body mounted upon said rollers so as to roll along the same in a direct-ion transverse, to the underframc and means for moving the body in suchlransverse direction to a position where the body can; be swung from a horizontal to a, full. tilted, position, the center of gravity of the earhody and the load contained therein being so positioned, the body being mounted upon illLMUill'l Pifl frame in such a, manner and the body mor ing means being so constructed and arran ed that during the first portion of the tilting movement the body will swing about or on a part of said rollers as l'tlClCt-EPS whereby said renter of gravity will fall, and so that during the latter part of the movement oi tilting the car body and the rollers as rockers will, be rest rained whereby the farther lllOVement of the body will raise the center of notches of the rollers roll along the same in a body at each end thereoi transver.-=el y exincense gravity and there will be converted intopotcntial energy the kinetic energy acquired during the first portion of the tilting movement of the car body.

24. A. dumping car having an underrollers 'that move transversely relative to the nnderfr'ame, and operating mechanhnn for moving the body transversely relative to the nnderframe and constructed so as to restrain thebody against outward movement when the body is at or near the extremity of its sidewise or outward travel, the body having teeth or projections that engage the and being controlled by said operating mechanism is such a mannor that kinetic energy acquired by the body during the first portion'of the tilting movement is converted into potential energy during thelast portion of the movement of the body to full tilted position.

A dumping car of the class described comprising in combination an, under-frame having honizontally and transversely extending tracks, a pair of rollers mounted upon and movable along each oisaid tracks, a body mounted upon said rollers so asto' direction transverse to the undertrame, and operating mechanism for moving the body in said transverse direction to a position where the body can be swung from a horizontalto a full tilting position, the center of gravity of the'car and the load .()l'll'.lifl0(l therein being so posilioncd, the body being mounted upon the under-frame in such a manner and the operating mechanism being constructed and arranged so that during the first portion of the tilting movement the body will swing about a part of said rollers as rockers, and so that during the ast 'phrt ot' the movement of the car body toward 'i'ull lilting position further outward movement oi the car body and of the rollers will borestraiinad in such a manner that the continued angular movement of the rar body will be such that the car body will roll on the rollers which served as roclc ers in a manner to prevent a falling of the center oi gravity of the car body and its load whereby there will he a converting into potential energy during the latter part of the tilting movement oi kinetic energy acquired during the previous portion of the movement of the car body.
